For compound planetaries, the second stage will have a 'Module multiplier'.

For example, if you have a planetary with 3 planets and a 'Rotate planets by multiple of' of 60°, only one of the rotations of the planets in the set 0°, 60°, 120° will make the planet mesh. do this by rotating the planet by a multiple of the angle shown by the generator.

After you have created your 3 gears and have the planet meshing with both the sun and ring gear and you create a circular pattern you will often have to rotate the other planets to make them mesh.If you are using this generator to create helical gears make sure to use the radial system, otherwise, you will have to divide the 'Planet distance from center' by the cosine of the helix angle for it to be correct.I highly recommend the Helical Gear Generator add-in for fusion 360 by Ross Korsky if you are using it, otherwise by Abel Vincze. To generate the gears, you can use one of many other generators. The module has to be the same for all gears in each stage. This generator doesn't generate the actual gears themselves, instead it generates their teeth count so you can generate them yourself.Please choose which type you want to generate below. A compound planetary gear consists of multiple simple planetary gears in so-called 'Stages'. A simple planetary gear consists of a ring gear, a sun gear, and multiple planet gears, where typically the sun is the input and the planet carrier is the output. This is a generator for simple planetary gears and compound planetary gears.
